I received a 6.3 volt capacitor (the blue one on your parts list) from adafruit industries in the mail but the one that you show is a 10 volt. Will mine still work for this project? Also, do I need one or two of them?, because you stated 1 for quantity here on your parts list but show two of them on the next step. And is an on/off switch absolutely neccessary?, because I didn't receive one of those in my kit either. Lastly, I received only one transistor, you show two. What should I do?

6.3 V cap will be ok since you're gonna work with a 1.5V battery ...
(the voltage on those electrolytic caps is the maximum you can use them with)

The materials shouldn't cost more than $20 (US).. Looks like the priciest item is the copper foil tape, and you might be able to shop around a bit to find a decent deal.

Hi! What is the price of all the parts and do you where can i get them if i am not in the USA (cause i`m in Bulgaria)?
